Description

Welcome to the WLCG Open Technical Forum (OTF).

The WLCG Technical Coordination Board (TCB) is responsible for the technical evolution of WLCG services in line with the needs of the experiments and the capabilities of the infrastructure providers. The TCB defines a multi-year roadmap for such evolution and is responsible for its implementation. The TCB achieves these goals with a bottom-up approach through an Open Technical Forum (OTF) which welcomes the participation of all contributors to the technical evolution in the WLCG community.

Organizational matters:

If you require a visitor pass, please request via the registration form.
Please register only if you plan to attend in person.
Coffee/Tea will be served starting 30mins before the meeting (from 14:30 on Tuesday, and from 13:30 on Wednesday)
